Introduction 



Introduction 

It may be in ordinary day or night in familiar surroundings, but sit down with 
32K bytes of RAM in your TRS-M and pop in a ZORK diskette. You air plunged

About Your ZORK Diskette 

Although liua manual describes both lheTRS-80 Model I and Model II) versions 
of ZORK. only one ZORK diskette was included in your program package. 
Follow only the manual's instructions which apply to your computer and disk 
system. 

TTiisgame is BACKUP LIMITED to allow making only one copy of the game in 
addition to the original program diskette included in this package. Once the 
BACKUP process is complete, you cannot make another copy. It la important 
that you use this BACKUP copy of the program diskette when possible. Store 
the original diskette in its protective sleeve and put it in a safe place. 

If you have made your copy of the ZORK diskette, and try to make an addi* 
tional copy, the program will indicate that it cannot be done. 

Model I will display the message: 

INS1ALLWHIIF PH0TFC1 1AB 
1YPEANYKIY TO CONTINUE. 

Model III will display:

Backing Up ZORK 

You should read these instructions for backing up your program diskette care- 
fully before you actually perform any of the steps. 



Model I ZORK 

You can use only one drive (Drive 0) to perform the following backup procedure 
no matter how many drives you have in your system. 



Backing Up ZORK 



1) Follow the instructions in Appendix D to FORMAT a blank diskette. 

2) Remove the write-protect tab from the ZORK program diskette and put the 
diskette in Drive 0> 

3) Press and continue to hold any key on the keyboard. At the same time, press 



and release the RESET | button to begin the game. The program responds;

4} Release the key you've been holding. Preea any key to begin the backup 
process. 

6) When ready, the program prompts you to insert the backup (storage) destina- 
tion diskette. Remove the program diskette from Drive and replace it with 
the destination diskette. 

61 Type any key to continue the process. When ready, the program prompts you 
to re-insert the program (master) diskette. Since the program reads 1/4 of the 
diskette at a time, you will have to repeat steps 6 and 6 three times. 

71 When finished, the program prompts you to replace the write-protect tab. 
Label the Backup copy, and put a write-protect tab on both the original 
ZORK program diskette and the Backup copy* You should store the original 
diskette in a safe place. 

If there axe any problems during the Backup process, the program prompts you. 
You should re-format your destination diskette and try the process again. 



Model HI ZORK - Single-Drive 

Use this procedure EXACTLY: 
Note: You must have a destination disk ready upon which to Backup ZORK. 

1) Turn on your system. If this is the first time you've ever used the Radio 
Shack Disk System, refer to the Disk System Owner's Manual for detailed 
instructions. 

2) Insert the original program diskette to be Backed Up in Drive 0* Hie 
diskette MUST NOT have a write protect tab on the notch at this time.

It is assumed that you have read about the general operational procedures for 
your computer system in your Owner's Manual, and that you now know how to 
turn the power on, etc* 

ZORK allows you to save your game position any time during the game, in case 
you get lost or killed. To save a game position you must use a storage diskette 
that has been formatted before you begin playing ZORK. Appendix D contains 
detailed instructions on how to format a Model 1 storage diskette. Appendix E 
contains instructions for Model III diskettes.

Rules and Strategies 

The Cereal Cndergrouad Empire 

In The Great Underground Empire you arc near a great underground 
labyrinth, which is reputed to contain vast quantities of treasure. No doubt, 
you wish to acquire some of it. In order to receive full credit for treasure, you 
must deposit it safely in the trophy case. 

In addition to treasure, the labyrinth contains various objects that may or may 
not be useful in your attempt to acquire the treasure. You may need sources of 
light, since caves arc often dark, and weapons, since dungeons often have 
unfriendly beings wandering about in them. Reading material is scattered 
around as well, and you might even find some of it useful. 

Beware of the thief! lie is a dastardly antisocial type and a skilled 
pickpocket. Watch out for your valuable possessions when he is near. 

To measure your success. ZORK keeps track of your score. You receive points 
for finding treasure, for securing it in the trophy case, for performing certain 
actions, and for visiting certain places. There is a penalty for getting yourself 
killed. 

In thin story, time passe* only in response lo your input. You might imagine a 
giant clock that ticks once per move and the story programed only at each tick. 
Nothing happens in the ntory while you ore thinking and planning your next 
move, so you can plan your moves slowly and carefully if you so choose. 

TTie line displayed at the top of your screen tells you the room you are in, your 
current score and how many moves it took you to achieve this: 

HDOM: SCORE MOVFS, 

Concept! for Exploring 

Some things that you can do with objects in this story are not immediately 
obvious. 

Containment: Some objects can contain other objects. Some containers can be 
opened or closed, and some are always open. Some are transparent, and some are 
not. Most containers have a limited capacity, and all objects have sizes, so that 
it is possible to fill up containers. Similarly, some objects have surfaces on which 
other objects can be placed. 

Fighting: Characters in the story will, a* a rule, fight back when attacked. They 
may. in some cases, attack you unprovoked. Some of these beings are stronger 
than others; it might be advisable to wail a while before taking them on. 



Rules and Strategies 



Emerging second-best in a fight may leave you somewhat the worae for wear: 
you might want to ask ZORK to diagnose your condition (see Appendix B. 
"Command Summary"!* 

Vehicle*: There an- objects in the story that have the ability U> tranaport the 
fearless player to mysterious regions thot arc inaccessible on foot. Needless to 
say, one faces great personal peril in venturing into such regions. 

Directions: The passages connecting rooms in The Great Underground Empire 
sometime* twist and turn unpredictably. You cannot expect that after going 
north, you can always return to where you were by going south. 

Talkiag lo ZORK 

When you play a ZORK game, you talk to ZORK in plain English, by typing in 
all your request* on your computer a keyboard when you see the prompt \>l 
(ZORK allows you to abbreviate some words because you use them often.) When 
you have finished typing a line, press the I ENTER] key and ZORK will consider 
your request. 

ZORK usually acta as though your sentence begins with ''I want to ../\ 
although you should not type these exact words, ZORK then displaya a response 
that tells you whether what you want to do is possible in the current situation, 
and. if it is. whether anything interesting happens as a result. 

All words you type are distinguished by their first six letters and all subsequent 
letters are ignored. For example, typing Open the encyclopedia in equivalent to 
typing Open the encycl or better still. Open the book. ZORK doesn't care 
whether you type in capital letters or lower case letters, or a mixture. 

ZORK understands many different types of sentences. A sentence must contain 
a verb and usually an object. Some examples: 

Take the gold Drop gold. Pick up gold. Put down the gold. Go north, North. 
Walk north. N, Puah button. Push the rod button. Opan wooden door. Look at 
tha wa*. Look undar rock. Look behind curtain. Look In bag. Read a book. Bead 
aH of the books. Drop ad. Take all. Drop all but the knlfa. 

You muat separate multiple objects of a verb by the word "and" or a comma (.), 

Teka all but the knlfa and the lamp. Put tha gold and jewsU In the trophy case. 
Throw tha newspaper, the red book, and tha magazine In tha chasm. 

You can include several sentences in one input line if you separate them by the 
word then or a period. You don't nocd to type a period at the end of an input 
line. For example: 



u 



Rules and Strategies 



12 



Take book. N P Drop book and candle. 

Take the book then N. Drop book and candle 

There are only two kind a of questions that ZORK understands: What and 
Where. For example: 

Where la the gold? What la a grue? 

ZORK tries to be clever about what you really mean when you don't give enough 
information. If you say that you want to do something, but you don't say what 
to do it with or to. ZORK will sometimes dedde that there was only one possible 
object you could have meant. When it does dedde. it will tell you. by displaying, 
for example, (with \T\e rope). If your sentence is really ambiguous, ZORK will 
ask you what you really meant- ZORK may ask. for example. With what?; this 
can be answered briefly, by typing [p T] [p] je] . 

In a way. ZORK's vocabulary is lopsided, because ZORK usee many more words 
than it understands. ZORK's vocabulary consists of several hundred words, and 
includes nearly all the words that you are likely to use in conversing with ZORK. 
However, ZORK's responses may be quite elaborate at times, and ZORK will 
display English descriptions that it couldn't possibly analyze. Indeed. ZORK's 
response may refer to something to which you cannot refer (perhaps to your 
dismay). In that case, it is not essential to the story, and appears in ZORK's 
responses only to enhance your mental imagery* 

Completely mystifying sentences will cause ZORK to complain in one way or 
another, and, after making the complaint, ZORK will ignore the rest of the input 
line. Unusual eventa. such as being attacked, will also make ZORK ignore the 
rest of the sentences you typed, since the event may have changed your situation 
drastically. 

ZORK's Pedagogy 

ZORK may occasionally have a few words for you when it wants you to clarify 
an instruction you've given. Some of ZORK's remarks are: 

I don't know the word '(your word)'.— T*e word you typed is not in the game's 
vocabulary. Sometime* a synonym or rephrasing wlU be undentlood. If not, 
ZORK probably doesn't know the idea you were trying to get across. 

I can't us© the word '(your word)' here. -ZORK knows the word you typed, 
but the word made no sense where you put it in the sentence: Open trie take, for 
example. 

You must supply a verb!— Unless you are answering a question, each sentence 
must have a verb (or a command) in it somewhere. 



Rules and Strategies 



There is a noun missing in thai sentence— This usually indicate* an incomplete 
sentence, such aa Put the lamp In the , where ZORK expected another noun and 
couldn't find one. 

Too many noun clauses.— An example ia: Put the troH In the basket whh the 
shovel. A legal sentence has, at moat, one direct object and one indirect object. 



pardon?— You did not type anything after the prompt I > ) or before you 

pressed the P EWTE R"] key on your keyboard. 

It's too dark to see.— In the story, there was no light to see object* in the room. 

I cannot see any (object) hero.— In the story, the object you referred to was not 
accessible to you. 

Multiple objects cannot be used with (youf verb).— It la valid for you to use 
multiple objects (that is. nouns or noun phraaee separated by "and" or a comma) 
only with certain verba. Among the more useful of these verbs are take. drop, 
and put. 

I don't understand that sentence.— You typed a sentence that ia gibberish to 
ZORK. for example. Give troi with sword. You might try rephrasing the 
sentence. 

Commands for Exploring 

The best way to move from place to place is to type the direction you want to 
go. Acceptable directions are North or N. South or S. East or E. West or W. NE 
for Northeast or NW. SE» SW (for Northwest. Southeast or Southwest respec- 
tively). U or Up. and D or Down. 

When you enter a particular place (ZORK calls any kind of a place a "room") far 
the first time, ZORK usually displays the name of the room, a description of it. 
and then descriptions of any interesting objects In the room with which you 
might want to interact* When you return to a room. ZORK normally displays 
just the name of the room and the names of the objects in it The VERBOSE 
command tells ZORK to give the description of rooms and objects every time 
you go there, not just the first time. The BRIEF command tells ZORK to 
describe fully only newly encountered rooms and objects* For moving through 
areas you already know well, the SUPERBRIEF command tells ZORK to give 
only the name of s room (even on your first visit there), and not even to mention 
objects in the room. You can always get a deecription of the room you are in and 
the objects in it by typing E [o] [o] B (or the abbreviation [TJ>. 

Hint: Exploring The Great Underground Empire will be much easier if you make 
a map as you move around. 



Rules and Strategies 





list of ZORK Commands 




To simplify your adventuring, you may order ZORK to give you information by 
typing specific command*. TTiese commands can be used over and over again as 
needed, but they are each considered one complete move. 




The list of commands is: 




AGAIN 


ZORK will respond as if you had repeated your previous 
sentence. 




BRIEF 


This commands ZORK to fully describe only newly 
encountered rooms and objects. Rooms already visited and 
objects already seen will be described by printing the room 
name and the object names only. 




DIAGNOSE 


ZORK gives you a medical report of your physical condition. 
This ts particularly useful if you have just survived a 
dangerous battle. 




INVENTORY 


ZORK hats your possession*. If you ve noticed the thief 
lurking about, you might want to check to see if your 
belongings are still there. You may abbreviate 
INVENTORY by typing I. 




LOOK 


ZORK describes your surroundings in detail. You may 
abbreviate LOOK by typing L 




QUIT 


This gives you the option to quit playing. If you want to 
save your position, first read the instructions under "Saving 
a Game Position." You may abbreviate QUIT by typing Q. 




RESTART 


This ends the game and starts the game over from the 
beginning. 




RESTORE 


TTiis lets you pick up a game position from where you issued 
the last SAVE command. See the section on "Restoring a 
Game Position/' 




SAVE 


This lets you save your position in a game so you can come 
back to it later. See the section on "Saving a Game 
Position/* 




SCORE 


ZORK shows your current score with the number of moves 
you have made, and your rank. Your rank is your rating as a 
professional ZORK player and is based on the number of 
points you have and the number of moves you've made.

Rules and Strategies 



Thin command assumes you have a printer. It commands the 
printer to begin printing a transcript of your game session. 

This command tells ZORK to show you only the name of the 
room you have entered, and no other information. It is 
briefer than DRIER 

Unncript stops your printer from printing* 

This command tells ZOKK to show you a long description of 
the room and the objects in it whenever you enter a room. 

ZOKK responds by showing you the version and serial 
number of your copy of the game* 

This causes time in the game te pass. Normally, between 
moves, no time is passing as far as ZORK is concerned. You 
could leave your TRS-80. take a nap, and return to the game 
to find thai nothing has changed- WAIT is used when you 
want te find out what will happen in the game if you do 
nothing while time passes. For example, if you encounter an 
alien being, you could WAIT and see what it will do.
